' Infthe Netherlands January 23, 1942 section 1,-fPu'b1ie-Law 690, Auguste, 1946s Patentrexpire's January "23, 1962 4 Claims. (Cl. 1416-434) The object of Lthe-invention is to providefin f the conveyor drive a Vsafety-*device in orderf-to Aprevent "breakage of ordamageA to the driving mechanismv inthe event that movement-,ofthe conveyor is"obstruc'ted. For instance,- suchan obstruction'might occur with a spiked conveyor in the event that'a'cconveyor'spikegot bent'and fouled the slice guide. y

The" invention vcomprises aisli'cing machine of the' type' 'stated 'in which ythere is interposedb'etween' the conveyorand its driver ajyieldi'ng device by virtue of which the driverisrendered ineflectivein relation 'tothe conveyor if rotation thereof is resisted.

AThe invention also comprises a slicing machine off'the type stated in whichV the 'conveyor is connected to its driver by mechanismcomprising pivotalA members interconnected 'by a yielding device by virtue of whichUone of said members is movable in relation to the other ...so as torender the mechanism ineffective if rotation of the conveyor is resisted.`

The vyielding device may be ai springfwhich normally. maintains a one-way,drivingtconnec- Ation between the driver and the conveyor, during the slice conveying.-motinf; lbut-yields to resistanceimposed upon theconveyor, thus permitting the; driver toz continueits lmovement idly;

The driver and the-conveyor` may be connected through two oscillatoryconnectors, one=cf which has an abutment normally engaged by the other under the action of the yielding device, the arrangement being such that the connector connected to the conveyor stops its motion if the conveyor is stopped during the slice conveying motion by resistance, whereas by virtue of said device the connector connected to the driver continues its motion.

A slicing machine embodying the invention will now be described by way of example with reference to the accompanying drawing in which:

In Athe example, the slicingmachine-includes as usual a rotatable circular knife-2;"the axle =I of w-hich'is driven by-a motor or *by-handfb'eing Ajournalled in a knife-:bracket not shown) forming a component fof' ithe frameofl the-machine. The/substance to bel slicedI is vvcarried 'on accarriage'S which is-reciprocable past the Afront 'of the knife:

The drive of the slice conveyor includes a pinwith `a Agear wheel 5 -on--as'shaft'f This shaft has a disc' liinwhich is'formedY acamgroove engagedl by Va'cam-following'roller `8journal1ed 'at one 'end'ofa lever arm-9. Thisleverarm is associated *with another lever'including'an arm 8A; the Vend of-which is pivotally connectedrto a link IB which; in its turn,`is pivotally connected to a Ahorizontallyreciprocable rack *'II. This 4rack Il meshes with a pinionl2 onthe "shaft i3 of the slice `conveyor 15, vas shown clearly in Fig; '1f The'slice conveyor v-'l5 mayjioeofknown construction; itincludes spikes which; ind order topierc e' each* successive slice;v cooperate "with: a slice' guide I8 mountedbeh'ind the rk'nife' adjacent to 'the cutting"arc"th'ereof. The'sliceguide' I8 is formedwith grooves yor"slots"25 `whicl'ii are entered by'the conveyor spikes Vduring theirrslice piercing action;

The lever 'arm' Si is connected through 'asafety device (hereinafter described); toI the lever in'- cluding "the arm'BA." Thefcam disc 1" maybe regarded as `the driver'ofthe conveyonithe drive being transmittedto the' conveyor' through the `meel'ianisrn described.l The `conveyor performs a to-and-fro 'rotational' motion.'

The conveyor is also associated lwith a slice discharging fly'M which isturnabl'e about `astation'ary pvot'pin' I6; and which is" operatively `connected through -a 'link'i 'I "to a lever'2l provided side the lever arm 9. Both levers are fulcrumed on the same stationary pin I9. A tension spring 20 connects a projection 2I on` the lever arm 9 with a projection 22 on the other lever arm 9A. Under normal working conditions the lever 9, projection 2I and the lever 9A, projection 22, and arm 24 operate as a single unit, the arm 24 being maintained tightly against an abutment pin 23 of the arm 9 under the pull of the spring 20.. During the slice conveying motion of the conveyor, the drive is transmitted through the spring 20, which must be strong enough to force the spikes to pierce the hardest and thickest slices. During the return motion the drive is transmitted through a pin 23 to the arm 24.

Suppose that the conveyor meets an obstruction during its slice conveying motion; suppose, for instance, one or more of the spikes foul the slice guide I8. In that event the spring 20 yields before the resistance caused by the obstruction, thus permitting the driver 'I to continue its rotationandrthe lever 9 to continue its movement aboutthe fulcrum I9. On the other hand, the lever 9A, projection 22, and arm 24 is stopped, so that the normal engagement between the abutment pin 23 and the arm 24 is interrupted. This condition of the parts is illustrated vby Fig. 2, in which it will be seen that the arm 24 is held raised While the arm 9 has moved downwards under the action of the driver 1. Thus, when the vsafety device is brought into operation, the driver lk is rendered ineffective in relation to the conveyor for the time being. As soon as the obstruction is removed, normal operation of the conveyor continues.

o As aforesaid the machine shown in the drawing is an example. Accordingly, modications may be made. The invention is applicable to slicing machines in general of the type stated.

,Changes may be made in the form, construction and arrangement1v of the parts without departing from the spirit of the invention or sacri- Iicing any of its advantages, and the right is hereby reserved to make all such changes as fall fairly Ywithin the scope of the following claims.

The invention is hereby claimed as follows:

1. In a slicing machine, a pivotally mounted slice receiver, a 'pivotally mounted irst lever, a projection on said lever, means for actuating said lever, a pivotally mounted second lever, an operable connection between said second lever and said slicereceiver, and resilient means normally maintaining a part of said second lever in abutment with the projection on the rst lever where- `by the second lever may be actuated by the first lever to pivot said slice receiver under normal operating conditions, but permitting the second lever to move out of engagement with said projection when the slice receiver is overloaded. thereby operably disconnecting the slice receiver from the said lever actuating means.

2. In avslicing machine, a pivotally mounted slice receiver, a pivotally mounted rst lever, a Aprojection on said lever, cam means for oscillat- -ing said lever, a pivotally mounted second lever,

3. In a slicing machine, a pivotally mounted slice receiver, a pivotally mounted first lever, a projection on said lever, cam means for oscillating said lever, a pivotally mounted second lever, an operable connection between said second lever and said slice receiver, and a spring operably connected between said levers and normally maintaining a part of said second lever in abutment with the projection on the first lever whereby the second lever may be actuated by the first lever to pivot said slice receiver under normal operating conditions, but permitting the second lever to move out of engagement with said projection when the slice receiver is overloaded or is being obstructed, thereby operably disconnecting the slice receiver from the said lever oscillating means.

4. In a slicing machine, a pivotally mounted slice receiver, a pivotally mounted lever, a projection on said lever, cam means for oscillating said lever, a bell crank pivotally mounted intermediate its ends, an operable connection between one arm of said bell crank and said slice receiver, and spring means normally maintaining the other arm of said bell crank in abutment with the projection on said lever whereby the bell crank may be actuated by the lever to pivot said slice receiver under normal operating conditions, but permitting the last said arm of the bell crank to move out of engagement with said projection when the slice receiver is overloaded or is being obstructed, thereby operably disconnecting the slice receiver from the said lever oscillating means.
